Rampart Ridge (Snoqualmie)

Rampart Ridge is a moderate 6 mile rock scramble in the Snoqualmie Pass area, with 2,400 feet of elevation gain. The steep approach passes Lake Lillian and follows a series of tarns and heather benches before ending at the base of the rock rampart. Enjoy a scenic approach through open meadow terrain with wide ranging views of the middle Cascades and a short but interesting rock scramble on its summit block.

Driving Directions

Drive I-90 to the Hyak exit (Exit 54). Cross under the highway and turn right on onto the frontage road (Forest Road 4832). At ~3,330 ft turn left onto Forest Road 136 (spur road).  It's full of potholes and narrow but drivable to the hairpin switchback at 3,800 ft. Here is where the well-used way trail to Lillian Lake starts.

Approach & ascent

North Peak

Ascend the way trail to the junction with the Lake Lillian trail from Mount Margaret and turn left to Lake Lillian. Follow the way trail over a crease in the rock abutting the lake to the east (Technical 4 difficulty rating). Continue on the way trail up to the ridge northeast of the lake. As the trail drops down to the east of the ridge follow it down and around into the drainage to the southeast of the summit; or alternatively follow the ridge to the summit rock. If ascending the drainage, at a junction (~5,600 ft) where one trail descends to Rampart Lakes, take the branch uphill to the summit rock. The summit can be attained by a short scramble of the west face of the summit rock (Technical 5 difficulty rating). Alternatively, one could descend alongside of the summit block to its east and turn into an unusual terrain of stacked ledge systems (Technical 3 difficulty rating). An ascent up the west face could be followed by descent through the ledges, but don’t descend too far before curling around right and off the summit block. It's 6 miles round trip with 2,400 feet of elevation gain to a high point of 5,870 ft.  The difficulty is Strenuous 3, Technical 4.

Southeast Peak

This is Point 5606 on the Chikamin Peak USGS map.  It is less than 0.5 mile southeast of Lake Lillian.  Ascend the way trail to the junction with the Lake Lillian trail from Mount Margaret and turn left to Lake Lillian. Just before reaching the lake's outlet, follow a boot path heading south, then up and behind the rock block at the southern end of the lake.  Once on the ridge line, follow the southeast summit’s northwest ridge to the summit block.  The final ascent is made from the southeast after circling the summit block either clockwise, passing over the brushy top of one gully, or by a slightly longer counterclockwise route over meadow slopes. It's 4 miles round trip with 1,900 feet of elevation gain to a high point of 5,606 ft.  The difficulty is Strenuous 2, Technical 3.
